Analysis of Organotins Using Large Volume Injection Gas Chromatography-Mass Spectrometry Selected Ion Monitoring
This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations.
Organotins have been used in the shipping industry as protective paint coatings applied to the hulls of ships. However, trisubstituted organotin compounds decompose in water in a stepwise manner to less substituted compounds, down to inorganic tin. As a result of their toxicity at low concentrations, trisubstituted organotin compounds are regulated through global environmental quality standards. To ensure regulatory compliance and environmental protection, the industry must perform rigorous monitoring of these compounds. This article will discuss current European environmental quality standards and review traditional methods for analysing organotins and their limitations. An application example will be used to demonstrate the analytical capabilities of large volume injection gas chromatography-mass spectrometry selected ion monitoring (LVI GC–MS SIM) for analysing organotins.
Inside the Laboratory: The Richardson Group at the University of South Carolina
November 20th 2024In this edition of “Inside the Laboratory,” Susan Richardson of the University of South Carolina discusses her laboratory’s work with using electron ionization and chemical ionization with gas chromatography–mass spectrometry (GC–MS) to detect DBPs in complex environmental matrices, and how her work advances environmental analysis.
RAFA 2024 Highlights: Contemporary Food Contamination Analysis Using Chromatography
November 18th 2024A series of lectures focusing on emerging analytical techniques used to analyse food contamination took place on Wednesday 6 November 2024 at RAFA 2024 in Prague, Czech Republic. The session included new approaches for analysing per- and polyfluoroalkyl substances (PFAS), polychlorinated alkanes (PCAS), Mineral Oil Hydrocarbons (MOH), and short- and medium-chain chlorinated paraffins (SCCPs and MCCPs).
Pharmaceutical excipients, such as polyethylene glycol-based polymers, must be tested for the presence of ethylene oxide (EtO) and 1,4-dioxane as part of a safety assessment, according to USP Chapter <228>.
